Estimate unweighted tonal, broadband and total hover OASPL directly below a multirotor aircraft, using geometry, mass, rotor thrust coefficient and solidity. Use known values or input ranges, and view total-level polar …
Open calculatorHigh-order CAA and low-order CFD codes are used by the research group to study the complex flow fields around streamlined and bluff bodies. The high-order solver employs the same numerical schemes and non-reflective bou…
View recordSynthetic turbulence methods are developed in AANTC to reproduce turbulence with specific turbulence spectra. A new method of synthetic anisotropic turbulence by deriving a general form of anisotropic filter that gener…
View recordAn efficient boundary element method (BEM) solver has been developed at AANTC to compute the sound scattering from the objects, which can be acoustical hard or impedance walls. Reduced order modelling technologies are e…
View recordA rotor noise prediction method based on the Hanson model was developed to compute the tonal noise of rotors. The effects of unsteady modes on the noise radiation are considered. Also, the broadband noise is computed us…
View recordIn AANTC, an acoustic preserved artificial compressibility method is developed to compute the sound generation and propagation at low Mach numbers. It can account for the compressibility, which is related to the sound g…
